Very cool, too pricey for me though:

I like it ;D though I am a sucker for anything with an evacuated glass tube that glows, or gas filled, for nixies :) but this kit looks nice and well made when assembled, a little pricey but not too bad.
-
That's pricey for just a bare PCB kit.
-
Indeed, I had to look twice when I saw that price.

Friend of mine designed and built one last year, only with characters not the nice analog version. It can be difficult to get the nice small crt's , so first try to score those before you start.

i might have been tempted but swmbo is getting me a nixie clock kit for my birthday >:D

A much cheaper option is this one:

That analog clock will terribly burn in the phosphor if it runs 24/7

Agree! That's the reason I did not buy one until today.
But I love the look of these clocks - looking really great.
Cheers and Happy new year,

They definitely look cool and retro 8)
Happy new year to you too.

I have a nice small TV CRT from a Sony viewfinder, wonder if I can use that magnetic system to make a clock, or does anybody want it.

$145 on Kickstarter or $100 directly from his website....

Hmmm... am I missing something?

$45 ? 8)
kickstarter one is supposed to be a "new" version with better psu (it at least is now advertised as 220v capable)

damn that site hurts the eyes..

Now unplug the power cord , and insert the IC marked 12f629 into socket U6.
Unplug the power again , and insert the chip marked "7528" ( 20 pin ) into U3, noting the proper orientation, and the biggest chip marked 18f26K20 into U1.
Do you really need 2 PICs for this?

That PCB... (http://img.food.com/img/recipes/22/78/2/large/picrIZyXg.jpg) :wtf:

No, ITYM this one. (http://www.tamvalleydepot.com/images/600_hex_juicer_P3107914.jpg)

How long before just a plain old analog clock will be considered "Bring Back" worthy? I remember the first time a kid asked me to read a analog clock for her... We have lost as a society...
-
Looks to me like a good way to burn up rare cathode ray tubes. Maybe a switch could be incorporated to cut off the cathode current when you're not home?
I have a nice collection of DG7-32, 2AP1's and a couple dozen other CRT's ranging 1" diameter at about 5" diameter. Don't think I'll be making a clock out of any of them.
-
I think these clocks need screensavers. Maybe a bouncing clock like in the old days?

With a motor physically rotate the CRT from left to right 8)

I was going to say something about this but I didn't want to rain on his parade.
It looks like he got his 5 yo to lay it out or maybe it's someone who used to use Bishop graphics back in the 70's and this is his first entry into pcb layout using software.
Anyway you've got to give him points for trying. I like to see people having a go ;)

I know a few of 20 and 30 year olds that can't read a clock, or have to count around the hour marks with their finger.

Reminds me of an old Dave Allen sketch where he tries to teach a child to read a clock:
Now, there are three pointers, called hands. The first hand is the hour hand, the second hand is the minute hand, and the third hand is the second hand...
So, its twelve o'clock, and the hands are at the top. Then the minute hand moves round until it reaches the one. That one is five. Two is ten, three is fifteen, four is twenty, five is twenty-five, six is a half...
Now, be a good boy and learn how to read the clock, and I'll buy you a digital watch.

well when it does burn in you'll be able to use the clock without power and it will be right twice a day :-DD
-
the software could gradually move the clock display around within the crt to reduce burn-in

In the CRT Clock Kickstarter, the PCB looks so ugly I cannot look at it. Why can't people stick to tracks with an angle of pi/4? Why have bunch of different angles... Can anybody explain?
